Aortic Perigraft Seroma After Total Arch Replacement-A Diagnostic Challenge.

Perigraft seroma is a rare but important complication after aortic surgery. Clinical vigilance is required to differentiate this collection from more serious conditions that warrant surgical intervention. We present the case of a 25-year-old man with Marfan syndrome in whom a large symptomatic aortic arch perigraft seroma developed after a fourth redo cardiac surgery for completion total arch replacement. Eighteen months after explorative mediastinotomy, he remains well with no recurrence of the collection.
